SPENCER RANCH
Spencer Ranch spans 43 acres in the Jackson Valley at the western edge of Amador County, surrounded by five lakes that moderate daytime heat. At night, cold air from the Sierras settles in the valley, creating a large temperature swing that imparts vibrant acidity to the wines. The vineyard sits on honcut sandy loam—a well-drained, granitic-based alluvial soil— yielding well-structured wines with naturally low to moderate yields.
Tim and Barbara Spencer acquired the ranch in 1970, seeking to return to farming despite having no prior experience with grapes or wine. By 1972, they had planted 30 acres of own-rooted Zinfandel and began selling the fruit to other wineries. In 1980, Tim consulted UC Davis and grafted five rows to traditional Portuguese port varieties: Bastardo, Touriga, Souzao, Tinta Cao, and Alvarelhao. Their first port production under the St.Amant label followed in 1981.
During the early 1990s, phyloxera required a full vineyard replant. Over the next decade, the site was redeveloped with new varieties, rootstocks, and trellises to ensure top-quality fruit. Today, Spencer Ranch encompasses 15 blocks of nine varieties—Verdelho, Tempranillo, Touriga Nacional, Touriga Franca, Souzao, Bastardo (Trousseau), Tinta Cao, Syrah, and Cabernet Sauvignon—each carefully cultivated for premium wine production.
MOHR-FRY RANCHES
“So God Made a Farmer” was Paul Harvey’s 1978 speech: “And on the 8th day, God looked down on His planned paradise and said, ‘I need a caretaker’—so God made a Farmer.” He describes the resilience, hard work, and character that define farmers: “It had to be somebody who’d plow deep and straight and not cut corners.” That speech reminds us of the foundational role farmers play in our nation’s character—a role that often goes overlooked and underappreciated. It’s the story of Lodi, and the story of Jerry and Bruce Fry.
Their family has been farming in California for over 170 years, and their Mohr-Fry Ranch Old Vine Zinfandel is our most popular wine. Their home ranch, just south of Lodi, encompasses 225 acres divided into nine blocks of own-rooted Old Vine Zinfandel, planted between 1901 and 1945. Each block is head-trained, own-rooted, and thrives in Lodi’s sandy soils, consistently producing what we consider some of California’s finest Zinfandel.
When we moved our winery to Lodi in 1996, our own vineyard was dying of phylloxera, leaving us with no grapes. My father struck an arrangement with the Lodi Winegrape Commission: if growers brought us two tons of grapes, we’d make the wine and give them 25 cases, keeping the rest. At the time, Lodi had only a handful of wineries, and most of its grapes went to large producers with no interest in showcasing Lodi.
Jerry Fry showed up with seven tons of Old Vine Zinfandel. My father didn’t have the money to pay for them and had no idea how the wine might turn out. Jerry said not to worry—we’d figure it out later. From that first vintage, we bottled 450 cases, won multiple awards, sold out, and created our most popular wine.
This story captures our bond with Mohr-Fry Ranches. To this day, we operate without a formal contract—just a handshake and a glass of Zinfandel. It’s the kind of partnership that drives our success, raises Lodi’s profile, and makes business fun. Our collaboration has expanded to include Mohr-Fry Ranches Petite Sirah, Alicante Bouschet, and a Heritage Red Blend. We’re also fortunate to source grapes from their Marian’s Vineyard, one of California’s most esteemed sites.

MARIAN'S VINEYARD
Marian’s Vineyard is an 8.3-acre own-rooted vineyard planted in 1901 at Mohr-Fry Ranch. Named after Marian Mohr Fry Zimmerman, the Fry family matriarch, the vineyard features deep, well-drained sandy loam soil, which produces low yields of exceptional quality fruit. Marian’s Vineyard was among the first six vineyards certified under the LODI RULES for Sustainable Winegrowing in 2005 and has been farmed as a no-till vineyard since 1997. Thanks to Bruce Fry’s meticulous care, this historic site consistently produces distinctive, high-quality fruit, resulting in a truly unique wine.

LEVENTINI VINEYARD
The Leventini Vineyard is the source of our delicious Barbera and Rose. The grapes come from a gnarled old vineyard planted in 1972 by our dear friend, and third-generation winegrower Ted Leventini. The vineyard is situated in sandy soils northeast of the City of Lodi in the Jahant AVA of the Lodi appellation. An ugly California sprawl with arms extending in every direction. Clusters that fit in the palm of your hand. It defies logic and proves that not all pretty vineyards make great wine, and sometimes ugly ones can make delicious wines that define their place.
Originally established for Gallo Hearty Burgundy back in the 1970’s. Ted had been pestering us for a number of years to make a Barbera, but we had plenty of unusual and lesser-known wines, that we really didn’t need another. However, Ted, an accomplished chef, ended up cooking for my wedding, and we felt obligated to make a little wine. In 1998 Ted snuck a few tons away from our southerly neighbor. The wine was an instant success–winning numerous awards and selling out in months, and has since been a mainstay of the St.Amant line of wine for nearly 30 years.

SHINN FARMS
Shinn Farms, managed by Aaron Shinn, is the latest addition to the St. Amant lineup and a cornerstone of our commitment to crafting exceptional wines. This Barbera vineyard, located in the Jahant AVA of the Lodi appellation, is the source of our Heritage Rosé and, starting in 2024, will become the sole source of our Barbera. Working with Aaron reinforces a core principle we hold dear: the grower is as critical as the vineyard site in creating delicious wines. Aaron’s dedication and expertise, combined with the unique character of this vineyard, ensure the production of wines that truly reflect their sense of place.

LLOYD MARTEL VINEYARD
This vineyard, planted in 1974 by our dear friends Lloyd and Jill Martel, is one of Lodi’s oldest Cabernet Sauvignon sites. Some might view the vineyard as flawed—it’s old, shows signs of virus, and yields have declined to minute levels. Yet, it is precisely these "flaws," combined with Lloyd and Jill’s meticulous care, that contribute to producing exceptional wine. At just 4.5 acres and located in their backyard, the Martels are constantly walking the rows, tending to each vine with precision. The results speak for themselves: rich, character-filled wines with a true sense of place.
Lloyd Martel was one of my dad’s closest friends, an agricultural teacher, and a local winegrower. A true pioneer in Lodi, Lloyd planted one of the first Cabernet Sauvignon vineyards in the region and played a key role in elevating Lodi wine with his early efforts. In the 1980s, he produced one of the first vineyard-designated Lodi wines, made at Mayacamas Vineyards by his friend Bob Travers. The two shared a history, having worked together at Heitz Vineyards in 1968.
Lloyd’s passion for wine extended beyond farming. For decades, he taught a popular wine appreciation class at the local community college. My parents took his class in 1974, where Lloyd flunked my dad (he missed the final due to work), but my mom earned an A. Despite that, Lloyd and my dad became the best of friends, sharing countless adventures—including delivering Cabernet grapes to Mayacamas Vineyards in 1982. The vineyard, with its rich history and extraordinary care, continues to produce wines that celebrate Lloyd and Jill’s legacy.
